Disco 2 help me please

Hello, my 2003 year discovery 2 has 4.0 V8 engine. The car has hunting. At high RPM the receipt of engine check is flashing and is loosing power. I have changed spark plugs, spark plug wires,ignition coils, injectors, fipl,detonation sensor but it is not fixed.when I plug in OBD it writes sometimes about second barrel and sometimes about seventh barrel. It shows problem of differrent barrel every time.Sparks are getting black. Plese let me know if anyone can give an advice. In my country noone could find out the reason

Try posting in the v8 engine section as we are mostly doozer drivers here. Best of luck

Everyone has been telling him to post elsewhere for a month


@Giorgier what ‘OBD plug in’ are you using

does it write a ‘code’ ?
